As of 2022, I am an Assistant Professor at the Cheriton School of Computer Science at the University of Waterloo, a member of the CrySP group, and Interim Associate Director of the Waterloo Cybersecurity and Privacy Institute (CPI) since March 2024. I completed my PhD on Information Systems and Computer Engineering at Instituto Superior Técnico (IST) - Universidade de Lisboa, under the kind supervision of Prof. Luís Rodrigues and Prof. Nuno Santos. During this time, I conducted most of my research at the Distributed Systems Group at INESC-ID Lisboa but also had the chance to undertake a research internship at Carnegie Mellon University under the supervision of Prof. Nicolas Christin. In late 2021, I was fortunate enough to become a post-doc at Rice University under the supervision of Prof. Ang Chen. My track record counts with over 25 peer-reviewed publications, including top venues for computer and communications security (IEEE S&P, ACM CCS, USENIX Security, NDSS), as well as other venues such as PETS, the world’s premier forum dedicated to computer privacy.
My Curriculum Vitae can be found in this link.
Research interests: My research is focused in network security and privacy, with particular emphasis on statistical traffic analysis and Internet censorship circumvention. I take additional interest in digital forensics.
